The structure of the reforested mangrove community in Brgy. [village] Gulod, Calatagan, Batangas [Philippines] was determined through assessment of physico-chemical parameters such as dissolved oxygen (DO), pH, salinity, and electrical conductivity and species composition and diversity using Point-Centered Quarter Method (PCQM). The mangrove area was divided into two sites, namely, edge and interior. Results showed that the mangrove forest is exposed to low DO level and high pH, salinity, and conductivity. A total of five species were recorded from the whole area. Edge site is more diverse with species richness of (S=5) and Simpson Index of Diversity (SID) of 0.23 compared to the interior site (S=3; SID=0.41) which was dominated by Avicenia oepata showing higher tree density (193 trees/ha). PCQM is subjective sampling thus the use of other sampling techniques and increasing the sampling size are recommended to determine the density and diversity of the mangrove ecosystem.
